20 Most Recent Panasonic VIERA TC-P55ST50 55 in. 3D Plasma HDTV - Page 9 Questions & Answers

Could be something as simple as the LCD driver board, ~$50 on eBay + whatever price for a service manual. My advice is research the specific symptoms, see what the max replacement hardware would cost and base your decision on that. In your model, LG is the hardware maker so the unit is fairly common. I'm doing the same thing right now for a Panasonic plasma and the fault is in one of three sub boards. It's an easy matter of pull and replace.

The pop noise was the fuse on the power supply board. You cannot use part substitutions like you are thinking. The only model substitions that you can use are all p60s30XX

HI Jimmy,
It is the power supply board which goes bad in such cases. Open the back cover and check if you can. You might get away with a blown fuse only. Good luck.

Connect audio out from tv to input of surround receiver. May require pulling up tv menu and turning off tv speakers.
